METHOD OF CLEANING BOILER EQUIPMENT INNER SURFACES FROM DEPOSITS Russian patent published in 2020 - IPC F28G9/00 

Abstract RU 2724063 C1

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used for physical and chemical cleaning of internal heating surfaces of boiler equipment from deposits occurring during operation. Method involves multiple circulation of a solution containing up to 30 % orthophosphoric acid, 10–30 % citric acid, the rest is process water. Solution is heated to 100 °C by ignition of the boiler and circulates for at least 12 hours with constant maintenance of acid concentration.

EFFECT: method effectively clears boilers from deposits density up to 2,500 kg/m3.
